摘要： A castable refractory mix composition is disclosed which when fired at a temperature of about 2300.degree. F. will yield a cast refractory article having improved thermal shock resistance and when fired at a higher temperature of about 2750.degree. F. will yield a cast refractory article having improved abrasion resistance. The castable refractory mix composition comprises from about 10 to 15% by weight of an aqueous slip of fine ground fused silica particles, from 25% to 32% by weight of fine alumina particles, from about 55 to 70% by weight of relatively large particle size silican carbide refractory particles, from about 0.015 to 0.04% by weight of a water-soluble wetting agent, and from 0 to about 5% by weight added water.
